MANCHESTER — A Manchester man who is serving a year in jail for the accidental death of his friend in 2010 is being sued by his friend’s family for wrongful death.

Nicholas Bell, 25, of Manchester, shot Jeffrey Charbonneau, 24, also of Manchester, with a .22-caliber rifle that Bell thought was an air rifle on Thanksgiving day in 2010.

In June, Bell was sentenced to serve a year in jail after pleading no contest in May to a felony charge of manslaughter and misdemeanor charges of simple assault with a weapon and reckless endangerment.

The complaint, filed on behalf of the Charbonneau, asks for unspecified damages because Bell “negligently” caused Charbonneau’s death.

In a brief response, Bell said he “accidentally” caused Charbonneau’s death.

Bell and Charbonneau were staying at the home of James and Carolyn Goodwin on Nov. 25, 2010, when Charbonneau was killed. His family has also filed a lawsuit against the Goodwins for keeping a firearm in an “unsecured and unsafe posture” in the bedroom in which Bell and Charbonneau spent the night.
